Sure - attached below:
I also noticed that I forgot to run it by checkpatch. It wasn't bad, but

Subject: [PATCH] ASoC: machine driver for Toshiba e750
This patch adds support for the wm9705 ac97 codec as used in the Toshiba
e750
PDA. It includes support for powering up / down the external headphone and
speaker amplifiers on this machine.

1.5.6.5
From aa97a30fdc180c73d7af89debb3324f598ec5705 Mon Sep 17 00:00:00 2001
From: Ian Molton <ian at mnementh.co.uk>
Date: Thu, 8 Jan 2009 21:16:05 +0000
Subject: [PATCH] ASoC: machine driver for Toshiba e800
This patch adds support for the wm9712 ac97 codec as used in the Toshiba
e800
PDA. It includes support for powering up / down the external headphone and
speaker amplifiers on this machine.
Signed-off-by: Ian Molton <ian at mnementh.co.uk>
